I just learned of a major management shakeup at testing leader Spirent. I rarely see something like this happen -- a wholesale replacement of so many managers and executives. The last year or so has been quiet for this company from a PR and marketing standpoint and many people were wondering what was going on with the company. It would seem now according to this article the company may be broken up into pieces. The testing market has a bright future but it seems this past quarter may have been underwhelming for a few players in the industry.
